50 * 0.06 = 3
1 - 0.06 = 0.94
94% loss. My bad, I was off 2%
Not quite, since unlike NXT, which is completely premined, LTC has had relatively high inflation from the time it was at $42 or whatever until now. Since the discussion was around the market cap of NXT, that would be the more apt point of comparison. Litecoin's ath market cap is ~768M and is now at around 138M, which is drop of about 80%, still a lot, but you were off by a bit more than 2%.
That doesn't reassure the hodler from the peak who lost 94% of their value with respect to fiat.
